This is a baseband receiver, located in a rural area of the German uplands (Sauerland) with the radio bandwidth of 48 kHz being converted directly by an ADC with 96 kHz sampling rate.
The whole thing is part of the PA3FWM WebSDR project and operated by Sabine, DL1DBC.

*** Maintenance works going on
I installed a new dipole e-field probe with strictly balanced signal processing. The very noisy workstation was replaced.
Parts of the heavy noise outbreaks still visible lowering the signal to noise ratio seem to be the result of moisture on the experimental PCB lacking a water-tight enclosure. There is still a lot to be done!
